f invention pertailistogautoinatic Q sewer iiushers ofthe type in which 'a' flushing appliance is setinf af manhole and connected to a sewer toperiodically discharge: the desired quantity offluslii-ng' water! j In i'n'stalling the(` automatic llusliers the contractor building the manhole or the sewer, Oi" both Vwhere they are.mad'ein` the same general constrhction, fits a' frame 'm the manhole construct-ion upon which theA 'flushingrapparatns 'is'V installed.: As the frame" frequently 'is not" level,- it entai-ls'con siderable di'iculty in leveling` thev floor of the flushing device wheninstalling same.=

An object of my invention is a simple construbtionl of vfloor Connection to the frame so that the floor may be properly leveled so that the flushing mechanism may operate properly. In the type of flushing mechanism with which my floor is generally connected it is necessary that the operating devices, such as a rod connected to a tilting pan and a bell valve, operate in vertical lines to prevent binding or the like and to allow proper working of the iiuslnng apparatus. j My invention may be considered as an im-` provement on that of Garrie H. Burns #1,256,656, issued February 19, 1918. The particular improvement in the floor comprises using a T-shaped frame which is built into the masonry of the manhole, or the well connected therewith. The platform, which preferably has an upper surface of wood, is adjusted by adjusting screws which ongage an internal flange of the frame and may be utilized to adjust the floor in a horizontal position. I

My invention lis illustrated in the accompanying drawings, in which: Figure 1 is a vertical section through a manhole and sewer well illustrating my floor construction with the general type of flushing device set forth in the above noted patent.

Figure 2 is a horizontal section on the @line 2 2 of Fig. 1 giving the plan view of the floor.

Figure 3 is a vertical transverse section on the line3-3 of Fig. 2 in the direction of the arrows. I

In the drawings the Well is indicated byl the numeral 1, being connected to sewers 2 and 3, or if the sewers are ofv large size the well may be connected to an opening in the top of same.V The manhole structure is des-l ea'. Ser-arma moet."

igliated byA the' `nuni'erzil4 "and the framing 5 is built i'nthe masonry at the'I top" oftlic I well. Thisframe isof T-shzipe and isusir? ally'cblstructcd with a relatively wide afnge 6 Veste'riding intoy the. masonry, a; vnarrow i'ang'e 7 eirtending voutwardly,` and a web 8 positioned vertically and substantially in the line of the wall of the manhole orwell. p

V f liefloor construction isronstructetl substantially as follows:

floor board 1`Ov "forms the base for supporting the flushing mecht'inisn'u,l hereunder described', and preferably hasa pair of straps 11 of noncorrodible metal securedonth'e under surfaceat each end or earchl side and heid-t the board- -by bolts 12. ory 'otherA suit able securing means. The board isprovided with a series of openings 18 and adjustingr bolts 14 are secured through the straps vor vbars 11 with the heads of the bolts fitting in the openings 13.'v The lower end of these bolts engage the inwardly projecting liange 7 of .the frame 5. In Apractice I find that rfour bolts are sufficient to properly level the floor and after it is properlyV leveled the openings 13 in the Vfloor boards are filled with some suitable composition indicated by the numeral 15, for which I find melted sulphur satisfactory. The peripheral edge 16 of the board around the web 8 of the frame is also filled with a suitable composition such as sulphur or the like, thus making a water tight jointb'etween theboard and the frame and also embedding the heads of the adjusting nuts 14.

In the type of flusher. illustrated a flushing column 17 is secured to the floor board, this cblumn being tubular and having a pan operating rod 18 extending therethrough, this being connected to thepan 19 which is pivotally connected. by an arm 20 to a bracket 21 bolted to the bottom of the floor. A lever 22 connected by a swivel rod 23 to the pan operating rod actuates the stem 24 of the-bell A In order that the Hushing mechanism may work properly it is necessary that the'floor be level so that the flushing column 17 will"V occupy a vertical position, and the pan operating rod and the stem 24 move inf'a vertical direction, thus preventing binding and unnecessary friction in the operation. As

` eveling'the floor simplifies the installationv and maintenance of the automatic sewer Hushersof the type set forth.

lIt isto be understood, vhovveventhat my invention may be applied to lushers of other types. f Various changes may be'made in the principles of In invention without departing from the spirit thereof, as set forth in the description, drawing and claims. Y y I claim: l 1,7111 a sewer lusher, la frame having an internal flange, a floor having straps secured.

thereto on the under surface, adjusting bolts extending `through said straps and resting on the iange, anda flushing mechanism on the floor.

2, In a Sewer ilusher, an vinverted Tf Se shaped frame, a; floor having a plurality of straps secured on its under surface, bolts threaded through said'straps, the bolt heads tting in openings in the floor, the ends of the bolts bearing on one of the flanges of the frame, means forming a tight seal at the bolts andbetween the ioor and the frame, and a lusher mounted on the floor. i

3. A sevverv flusher comprising in combina T-shaped frame having lateral flanges and a vertical Web, theouter flange. being en1- bedded in the manhole Walls, the inner flange extending inwardly, a vfloor having a plubolts threaded through said straps bearing on the inner flange, there being openings in the ioor for the vbolt heads, packing material in said openings surrounding the bolts and surrounding theperiphery of the VHooi` between same and the web of the frame, and

`flushing apparatus mounted on the tloor.A

VIn testimony whereof I lhave signed my name to thisspecification. 1
